  • 2 a section through a torsion damper for the drive train in 1 .
  • 3 an equivalent circuit diagram of a particularly preferred second embodiment of a drive train according to the invention with a particularly preferred second embodiment of a torsion damper according to the invention, and
  • 4 a section through a torsion damper for the drive train in 3 ,
  • In the in 1 shown equivalent circuit diagram of a particularly preferred first embodiment of a drive train according to the invention 100 are an internal combustion engine 102 and an electric machine 104 provided to a manual transmission 106 an output shaft 108 drive. The internal combustion engine 102 is preferably a 4-, 5- or 6-cylinder petrol or diesel engine. The electric machine 104 is an engine that allows both engine and generator operation. The manual transmission 106 is a transmission with five, six or seven forward gears. A reverse gear is not mandatory, as a reverse drive on the electric motor 104 is representable. If the drive over the internal combustion engine 102 takes place, put these as well as the E-machine 104 and the manual transmission 106 a three-mass system.
  • To rotational irregularities of the internal combustion engine 102 compensate is a torsion damper 110 provided according to a particularly preferred first embodiment of the invention, the input side 112 with a crankshaft (not shown) of the internal combustion engine 102 is rotationally connected and its output side 114 rotationally fixed to a Eingansseite 116 a clutch 118 connected. The coupling 118 is designed as a wet clutch. An exit side 120 the clutch 118 is non-rotating with a shaft 122 the electric machine 104 connected.
  • The torsion damper 110 who in 2 Shown in a simplified section is as a first spring and damping system 124 constructed in the manner of a two-mass flywheel, wherein a first rotational mass 126 at the exit side 114 is arranged. At this first rotation mass 126 supports a cage device 128 with several cages 130 off, these cages 130 the inclusion of compression springs 132 serve. The duck feathers are supported on one side 132 at the respective cage 130 The duck feathers are supported by their other side 132 over a central disk 134 and a hub 136 on a wave 138 off, with the shaft 138 as part of the clutch 118 can be trained.
  • The torsion damper 110 also has a centrifugal pendulum device 140 on, which can also be referred to as a centrifugal pendulum. This centrifugal pendulum device 140 has pendulum masses 142 . 144 on, which oscillate in curved paths in the centrifugal force field.

However, both the centrifugal pendulum device are located 140 as well as the cage device 128 with the compression springs 132 within through the first rotational mass 126 certain contour.
  • The mode of action of the powertrain shown is the following:
    One from the internal combustion engine 102 generated torque with superimposed alternating torque is first through the and he first rotational mass 126 (Flywheel) attached cage device 128 (Spring guide plates) on the compression springs 132 of the torsion damper 110 transferred and from the springs 132 on the one with the wave 138 Naked clutch (NAK) mounted hub 136 forwarded. This hub 136 and the central disk connected to it 134 are designed in outer diameter so that radially outside the spring set sufficient space is available to the centrifugal pendulum device 140 (the centrifugal pendulum) to attach it. This ensures that the alternating torque generated by the engine is already significantly reduced by the spring set, and that the centrifugal pendulum has a maximum effective radius and thus can muster a large counter-torque to the after the torsional still existing alternating torque. Because the hub 136 with the clutch closed 118 (NAK) directly with the electric motor 104 is connected, the counter-torque acts directly on the electric motor 104 and thus can by the resonance of the electric machine 104 significantly reduce induced vibrations.
  • It should be noted that between the electric motor 104 and the transmission 106 a second spring and damping system 146 is arranged.
  • The basis of the 3 shown powertrain 200 according to a particularly preferred second embodiment of the invention as well as provided therein, in 4 shown torsion damper 210 According to a particularly preferred second embodiment of the invention differ from the respective first embodiment only in details. Therefore, reference numerals are used for description, which are increased by 100 with respect to the respective first embodiment.

  • As in the first embodiment, also in the in 3 shown powertrain 200 an internal combustion engine 202 and an electric machine 204 provided, which serve over a manual transmission 206 an output shaft 208 drive. The internal combustion engine 202 is preferably a 4-, 5- or 6-cylinder petrol or diesel engine. The electric machine 204 is an engine that allows both engine and generator operation. The manual transmission 206 is a transmission with five, six or seven forward gears. A reverse gear is not mandatory, as a reverse drive on the electric motor 204 is representable. If the drive over the internal combustion engine 202 takes place, put these as well as the E-machine 204 and the manual transmission 206 a three-mass system.
  • To rotational irregularities of the internal combustion engine 202 compensate is a torsion damper 210 provided according to a particularly preferred first embodiment of the invention, the input side 212 with a crankshaft (not shown) of the internal combustion engine 202 is rotationally connected and its output side 214 rotationally fixed to a Eingansseite 216 a clutch 218 connected. The coupling 218 is designed as a wet clutch. An exit side 220 the clutch 218 is non-rotating with a shaft 222 the electric machine 204 connected.
  • The torsion damper 210 who in 4 Shown in a simplified section is as a first spring and damping system 224 constructed in the manner of a two-mass flywheel, wherein a first rotational mass 226 at the entrance side 212 is arranged.

This centrifugal pendulum device 240 has pendulum masses 242 . 244 on, which oscillate in curved paths in the centrifugal force field. Therefore, the frequency of the pendulum increases with speed and can cancel the rotational nonuniformity over the entire speed range.
  • In 4 is shown that the centrifugal pendulum device 240 radially outside the cage device 228 with the compression springs 232 is arranged in an axially same position. However, both the centrifugal pendulum device are located 240 as well as the cage device 228 with the compression springs 232 within through the first rotational mass 226 certain contour.
  • The mode of action of the powertrain shown 200 is the following:
    One from the internal combustion engine 202 generated torque with superimposed alternating torque is first by the at the first rotational mass 226 (at the flywheel) attached central ring 250 on the springs 232 of the torsion damper 210 transferred and from the springs 232 on the one with the wave 238 Cage device attached to the wet start clutch (NAK) 238 (Spring guide plates) forwarded. This cage device 238 (Spring guide plates) is designed in the outer diameter so that radially outside the spring set sufficient space is available to the centrifugal pendulum device 240 (the centrifugal pendulum) to attach it. Because the cage device 238 with the clutch closed 218 (NAK) directly with the electric motor 204 is connected, the counter-torque acts directly on the electric motor 204 and thus can by the resonance of the electric machine 204 significantly reduce induced vibrations
  • It should be noted that between the electric motor 204 and the transmission 206 a second spring and damping system 246 is arranged.
